The vertical Insta360 Quick Reader for your X3 action camera allows you to record footage onto the module and transfer it to your phone or computer without eating up additional camera battery. By inserting a microSD card into the reader and plugging it into the USB Type-C port of your X3, you can store data directly onto the device while you shoot. To preview and edit the footage while on the go, simply insert the Lightning or USB Type-C connector into a compatible mobile device and open the Insta360 app. Files can also be transferred and accessed through a personal computer.
